Description
Изобретение относитс к области па льного производства, в частности к флюсам дл низкотемпературной пайки, примен емым преимущественно при пайке узлов приборов из меди и латуни, в том числе с покрыти ми оловом, сплавами олово-висмут, олово-свинец. К таким узлам можно отнести термосистемы, термобаллоны, промывка внутренних объемов которых от остатков флюса после пайки св зана с большими трудност ми .The invention relates to the field of paired production, in particular, to fluxes for low-temperature soldering, used primarily for soldering copper and brass device assemblies, including those with tin coatings, tin-bismuth, tin-lead alloys. Thermal systems can be attributed to such nodes; thermoballoons, flushing of their internal volumes from flux residues after soldering is associated with great difficulties.
Известен флюс дл низкотемпературной пайки, содержащий, вес. %: Глицерин97-98Known flux for low-temperature soldering, containing, in weight. %: Glycerol97-98
Янтарнокислый аммоний 2-3 При использовании этого флюса затруднено вакуумирование замкнутых объемов после пайки и требуетс длительна операци по вакуумной сушке па нных узлов. Наиболее близким к предлагаемо.му изобретению вл етс флюс 2, который содержит ингредиенты в следующих количествах, вес. %:Ammonium succinate 2-3 When using this flux, it is difficult to evacuate the closed volumes after soldering and a long-term operation of vacuum drying of the soldered units is required. Closest to the proposed invention, the flux is 2, which contains the ingredients in the following amounts, wt. %:
Канифоль5-10Rosin5-10
Спирт этиловый80-90Ethyl alcohol80-90
Карбамид5-10Urea 5-10
Однако наличие канифоли в данном составе ограничивает его применение дл пайки узлов с замкнутыми объемами, например, тер.мосистем, термобаллонов, которые после пайки заполн ютс фрезонами, так как заполнитель-фреон раствор ет в процессе эксплуатации узла маскирующие микротечи па ного щва. Фреон вытекает из термосистемы и прибор выходит из стро .However, the presence of rosin in this composition limits its use for soldering of units with closed volumes, for example, thermal systems, thermal balloons, which after soldering are filled with freons, since the aggregate-freon dissolves masking microfluids during the operation of the node. Freon flows from the thermal system and the device is out of order.
Целью изобретени вл етс повышение качества пайки и облегчение вакуумировани замкнутых объемов па ных узлов.The aim of the invention is to improve the quality of soldering and facilitate the evacuation of closed volumes of soldered joints.
Поставленна цель достигаетс тем, что флюс дополнительно содержит аммоний салициловокислый и триэтаноламин при следующем соотнощении компонентов, вес. %:The goal is achieved by the fact that the flux additionally contains ammonium salicylate and triethanolamine at the following ratio of components, weight. %:
Карбамид5-10Urea 5-10
Аммоний салициловокислый8-10Ammonium salicylate 8-10
